This invention relates to niops.

Ohjects ot this invention are to provide a detachable niop in which abody portion is provided for the reception ot the prongs troni the mop.yand in 'which the mop prongs are not weakened adjacent their points ofengageinent with the attaufluueut. hut are lett intact for a materialdistance troni the niop itself and are lot-hed adjacent their extremeend, thus maintaining the integrity ot' the prongs and the strengththereof.

Further ohjccts are to provide means 1or quicklyY detaehinp1 the nloptroni the holder which may he Worked h'v nieans of a nut, and whichpositive in its action and prevents iiuulvertent loosening ot the mop.

Au euihodixneut ot the invention is shown in the accoxupanyineldrawings, in which Figurey l is a view ot' the mop in position on theattachment with parts in section.

Figure 2 is a longitudinal. sectional vieu' at right angles to Figure 1.

Figure 3 is a detail partlyY in section of the upper end ot the prongs.

Figure l is a transverse sectional vieu' on the line l--l ot Figure l.

The niop comprises a plurality of strands l which are folded over atransversely cX- tendine' bottoni har 2. and a correspoiulinp,v upperhar 3. The 'folded portion of the strands is enclosed hy ineans of afabric sheath i uliieh secured on opposite sides ot the liars liv meansot lines ot' stitching. as shown most elearlbv in Figures l and The hars"l have their terminals turned outwardlyT at righty angles to form theattaching' prongs 5. The eXtreine ends of these attaching' prongs aresecured together h v means ol a rivet G, as shown in Figure il. Anai'ierture 7 is formed adjacent the ends ot the prongs.

The holly portion comprises a shank 8 which is apertured. as shown inFigures 2 and Ll, to receive the prongs and to snugly hold the prongs insliding engagement. lt is to he noted that this apertnred shank 8 iselongated and houses substantially the entire vlength of the pron 11's,thus .securingI a very lirin attachment between the prongs and the hotlyportion.

The shank is provided with external threads l) upon which a rino' nut l0is screwed, as shown most clearlyv in Figures l and 2.

Further, it is to he noted that a channel 11 is formed in one side ofthe shank and houses a small rocker har 1'2 which is provided with anupturned lower end 13. The upper end ot the rocking har l2 is providedwith a.

lor-knipr finger adapted to enter the aperture 7. I

lt is to he noted that when the nut is screwed into its uppermostposition` that the locking linger 14 is held vin position within theaperture 'i against inadvertent detachnient. When the nut l() is seuvveel dou'nivardlv it engages the outwardly turned end 1B ot the har l2.and it rocks the linger 'l-l out of engagement with the aperture 7V,thus rcleaf-iingi1 the prongs 5 troni locking' engage` ment andpermitting;` the Withdrawal of the prongs troni the hotly portion.

lt is to he noted that the upper end oll the hotly portion is providedwith a slightlyY eonieal aperture l5 adapted to receive the conicalportion ,1G ot the handle li'. A screw i8 eX- tends into the handle andis conntersunk in the upper end of the body portion, as shown niostclearly in Figure 2, thus temporarily locking: the shank to the handle.

lt is to he noted particularlyY that the aperture 7 in the prongs 5 islocated adiaeent their eXtreme upper ends.y and that the shank S engagesthe prongs throughout substantiall)Y their entire xtent. This avoids theusual detects so eonunon in mops ot having the prongs weakened at theirpoints ot engagement With the hodlfiI portion.

lt will he seen that a niop has heen provided in which a i'ahric sheathwhollyv eucloses the metallic parts ot the mop and provides au upperrelatively hcavv portion wllieh may he used for scrubbing it desired.Further, this tahric sheath prevents dani-age to the oor hoard er toothoard or furniture in a room when the mop is used.

lt will he noted further that the niop nur v he vez-'v quickly andreadily detached trom the hodv portion by unscreiving the nut l0.

lt will he seen. theretore` that a detachable :nop has been providedwhieh is ot' extremely rugged and substantial Construction. and in whichthe parts may he most easily operated..

Although the invention has heen described in considerahle detail, it isto he understood that the invention nia)v hey variously embodied and is,theretore.y to he limited only as Claimed.

l claim:

ln a inop, the combination of a mop head having a. projecting' tongueprovided with a transverse aperture and a mop head holder having a shankprovided with a longitudinal aperture adapted to receive said tongue,said an externally located slot, a rocking bar With-n in said slot andhaving an outwardly pro- ]ecting cam portion, and a finger carried bysaid bar and adapted to be projected through 10 said transverseapertures to lock said tongue Within :said shank, said rocking berbeingstraight throughout its major portion, the straight portion of said barbeing normally located below the threads throughout the entire length 0fthe Straight portion.

In testimony that I claim the foregoing I have hereunto set my hand utMilwaukee, in the County Vof Milwaukee and State of Tisconsin.
